We make this a bit differently. Herring, layer of potatoes, shredded beets and shredded carrots. Repeat. Each layer divided by mayo, garlic, salt and pepper. Top layer is boiled grated egg and on the very top is shredded cheddar cheese. No onions. Served in a glass container, awesome colors and fantastic taste!

Very yummy though you do have to like beets and herring. I used herring that came with onions in sour cream. I sauteed my onions for fear of a strong raw onion taste that I am not fond of. Took some of akmommy23's advice to put mayo, salt, and pepper between each set of repeated layers and also added layers of hard-boiled egg. I think adding chopped walnuts or another very oily nut would be great.

My darling and I ran into a 2.50$ pack of smoked herring in the store, sniffed it and were transfixed. We had some leftovers of potato salad (with onion, lemon and vinegar) from the previous day, so I invested 1$ in a can of beets and microwaved the remaining baby carrots that were counting days on the bottom of our fridge. As the herrings were hellishly salty, I soaked them in water for 20-30 min and only used three pieces. I had some sour cream, so I added it to one of the potato layers. I also boiled two eggs and added them on top, with a thin layer of mayo, a pinch of dried parsley and two (leftover) lemon slices for decoration. I haven't added any more salt nor pepper, except for what was already in the potato salad and herrings. It was DIVINE. I will make this many times in the future.
Thank you for the wonderful recipe!

To remove excess salt herring, it must be cleaned and put it on 30 minutes in the milk.
And to remove the bitterness of the onion, chop it and place it in the boiling water.
Even sometimes add a thin layer of sweet-sour apple. It's not for everybody.
